As British summers become warmer, more homeowners are investing in air conditioning to stay comfortable. But many are unsure about the real difference between a portable unit and a fully installed system. While both cool the air, they differ significantly in performance, cost, noise and long-term value.
Below, Airvana’s engineers break down everything you need to know before making your decision.
What Is a Standalone Air Conditioning Unit?
A standalone air conditioning unit is a compact appliance designed to cool a single room. It contains both the evaporator and condenser inside one body, venting hot air outside through a hose. These units are plug-and-play, making them popular among tenants and short-term renters.
Prices typically range between £300–£700. They are ideal for smaller rooms of 20–25 m² but tend to be noisy because the compressor is indoors. They also consume more electricity over time compared with permanent systems.
What Is a Full Air Conditioning System?
A full air conditioning system is a fixed installation — usually a split system — where indoor units are connected to an outdoor condenser. This setup must be installed by an F-Gas certified engineer such as the Airvana team.
Split systems are the most common for homes, while ducted systems provide hidden, whole-home climate control. Modern systems offer extremely quiet performance, high energy efficiency and both heating and cooling.
Costs vary by property size, but typical prices include:
- Split systems: from £1,500 including installation
- Ducted systems: £5,000–£12,000 depending on layout
Comparing the Two: Key Considerations
- Cooling Capacity: Portable units cool single rooms only; full systems can cool entire homes.
- Installation: Standalone units require no installation; full systems require a professional engineer.
- Noise Levels: Portable units are louder due to internal compressors; full systems have quiet indoor units.
- Energy Efficiency: Full systems are far more efficient and cheaper to run.
- Aesthetics: Portable units take up floor space; full systems are sleek and discreet.
- Long-Term Cost: Portable units cost less upfront but more over time; full systems provide greater long-term value.
Which Option Is Best for You?
The right choice depends on your budget, property layout and long-term expectations. For renters or occasional use, a portable unit is convenient. For homeowners wanting lasting comfort, quiet operation and energy savings, a full Airvana-installed system is the best investment.
Hybrid and Alternative Options
Some homes benefit from a combination of both — for example, a split system in the main living area paired with a portable unit in a guest room. Multi-split systems allow multiple indoor units to connect to one outdoor condenser, offering flexibility with minimal exterior impact.
In listed or restricted properties, floor-mounted units or ceiling cassettes provide effective cooling while maintaining architectural requirements.
